REBRODUCER.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed June 19, 1920. Serial No. 390,241.

To all whom it may concern:

Be it known that I, ABRAHAM A'rLAs a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Reproducers, of which the following is a specification.

The invention relates to more particularly to the reproducers therefor, and has for an object to provide a re producer for reproducing vocal, instrumental or other sounds.

Among other features the invention comprehends a reproducer, designed to be cheaply manufactured and effectively produce sounds from the grooves or sound undulations of a phonograph record and to this end use is made of a body preferably carried on a suitable swinging support so that it can operate over the record and with the aid of a stylus produce the sound simu phonographs and lating the nature of the particular sound record from the same by instrumental or vocal production, the usual amplifier or horn being dispensed with.

In the further disclosure of the invention reference is to be had to the accompanying drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which,-

Figure 1 is a fragmentary side elevation showing the application of the reproducer.

ig. 2 is a'vertical longitudinal sectional view taken through the reproducer substantially on the line 22 in Fig. 1, and

Fig. 3 is a horizontal sectional view taken through the reproducer.

Referring more particularly to the views a phonograph 10 consisting substantially of the usual cabinet 11 in which is disposed a motor (not shown), connected with a spindle 1.2 for rotating a turn table 13 includes also an upright 14 on which is disposed a hori- Zontally swinging arm 15 in the nature of a support. the connection of the arm 15 with the upright 14 being such that a slight ver tical movement of the The usual phonograph record 16 1s disposed The reproducer consists substantially of a solid body 18 formed preferably in a single casting to provide an annular flange l9 and a medial comparativ ly the desired sounds will be reproduced and will be sufficiently clear and loud to be easily It has been found in actual practice that the provision of the cross open ing 21 in the diaphragm 20 and the particular relatively thin formation of the latter results in the production of sound of surprising clearness and loud tone and it will be readily seen that the simple construction of the reproducer and the very few parts compre ended in its make-up provide one which can be very cheaply manu factured and when combined with an instrument embodying merely a support, a turn table and a motor arranged in the cabinet for operating the turn table, permits of constructing an instrument at a minimum cost because among other reasons the usual delicate y constructed amplifier or horn is entirely eliminated.

aving described my invention, I claim 1. A talking machine reproducer comprising an integral body of circular shape and formed relatively thick with its central portion considerably reduced in thickness whereby to define a diaphragm, said diaphragm being formed with a central hole, and a socket member formed at a point in the periphery of said body and adapted to hold a stylus.

2. A talking machine reproducer comprising an integral body of circular shape and formed relatively thick with its central portion considerably reduced in thickness whereby to define a diaphragm, said diaphragm being formed with a central hole, socket member formed at a point in the periphery of said body and adapted to hold a stylus, said hole being tapered inwardly from both sides of the diaphragm.

In testimony whereof I aflix my signature.
